The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 684, 644, 869, 163

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(684, 644) = 110124

GCD(684, 644) = ( 684 x 644 ) / 110124

= 684 / 644

= 684

Step2:

LCM(4, 869) = 3476

GCD(4, 869) = ( 4 x 869 ) / 3476

= 4 / 869

= 4

Step3:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

So, Greatest Common Divisor of 684, 644, 869, 163 is 1
